run code in 300+ PHP versions simultaneously
<?php function check($value) { return (bool)preg_match('/^\p{Cyrillic}{1}$/', $value); }; $test = 'ะค'; var_dump(check($test));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
